BJP's success in bringing two divergent partners--DMDK and PMK--under NDA fold ensured votes did not split in a contest that it hopes would give it a significant number of members as it rides on the Narendra Modi wave in the wake of the Prime Ministerial nominee's two well-attended public rallies in the state.

The BJP-led combine comprised of actor-politician Vijayakant's DMDK, PMK founded by S Ramadoss, Vaiko-led MDMK and IJK and KMDK, two local parties, decided to join the NDA fold, burying their differences especially on their wish-list constituencies.

Elated over the seven-party rainbow alliance, BJP president Rajnath Singh described it as a "historic" moment not only for Tamil Nadu but also for the entire country to oust the Congress-led UPA which, he said, was immersed in a series of scams while leaving the economy in a "mess".

Announcing the alliance and also the constituencies allotted at a press conference here in the presence of leaders of its alliance parties, Singh said BJP stands for "coalition dharma" unlike Congress.

The BJP was committed for federal structure and it has already proved that it could run efficiently a coalition government during A B Vajpayee's regime, he said, assuring that the saffron party would respect its partners.

Interestingly, BJP managed to bring DMDK and PMK, parties which are poles apart, under the umbrella of the alliance which also comprises of MDMK, IJK and KMDK.

Under the seat-sharing agreement agreed upon by the allies, DMDK was given the lion's share of 14 out of 39 seats, followed by BJP and PMK at eight each. MDMK will be fighting from seven seats while IJK and KMDK will field candidates from one constituency each.

Singh made the announcement flanked by allies Vijayakanth (DMDK), Anbumani Ramadoss (PMK), Vaiko (MDMK) and Paariventhar and Easwaran from IJK and KMDK, respectively. However, PMK founder S Ramadoss was conspicuous by his absence.
